Why do my colorbars appear to be inappropriately and inconsistently sized in subplots in MATLAB 7.0 (R14)?

When I add a colorbar to my subplots, it can be inappropriately, and sometimes inconsistently sized. The width appears to be greater than that produced by earlier releases. As an example, use the following commands to produce a plot:

A = rand(100,100);

B = rand(100,100);

C = rand(100,100);

subplot (1, 3, 1); plot(A); colorbar;

subplot (1, 3, 2); plot(A); colorbar;

subplot (1, 3, 3); plot(A); colorbar;

This enhancement has been incorporated in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

As of MATLAB 7.0 (R14), the COLORBAR function included changes to provide more room for the colorbar, and to prevent the overlap of tick marks between adjacent plots. As a consequence, the size of the data axis is now smaller, which causes colorbars to sometimes appear disproportionately larger.

As a workaround, the behavior of earlier releases may be matched by passing 'v6' as a parameter to the COLORBAR function, as in the following example:

A = rand(100,100);

B = rand(100,100);

C = rand(100,100);

subplot (1, 3, 1); plot(A); colorbar('v6');

subplot (1, 3, 2); plot(A); colorbar('v6');

subplot (1, 3, 3); plot(A); colorbar('v6');
